MART/N C. BEPJTED BY ATTORNEY Patented Jan. 9, 1934 UNITED STATES PATENT oFFic 4 Claims.

My invention relates to water sprinklers and the objects of my invention are: First, to provide a sprinkler of this class in which all necessary adjustments, such as regulating the volume of water, and the direction of flow thereof, are made from the top or spray end of said sprinkler; second, to provide a water sprinkler in which the spraying jet may be shifted from one position to another while the sprinkler is in operation, thereby enabling said sprinkler to accurately spray the desired area, thus reducing to a minimum the waste of water; third, to provide a water sprinkler which is especially adapted for sloping ground where it is difficult to mount the sprinkler in a vertical position; fourth, to provide a water sprinkler which is extremely small relative to the area for which said sprinkler is adapted to spray, thereby providing a sprinkler which is practically unnoticeable and which does not mar the appearance of a lawn or the like; fifth, to provide a water sprinkler in which the jet members may be readily removed for replacement, repair or cleaning, without disturbing the lawn or other vegetation for which the sprinkler is adapted to spray; sixth, to provide a water sprinkler which eliminates the need of accurately positioning the pipe system therefor as said sprinkler may be easily adjusted in order to spray large or small or relatively awkward areas; seventh, to provide a water sprinkler in which the parts most apt to be damaged or most apt to wear may be readily and quickly replaced without disturbing the sprinkling system, and, eighth, to provide a water sprinkler which is extremely simple of manufacture, durable, eflicient in its action,

compact, and which will not readily deteriorate or get out of order.

With these and other objects in view as will appear hereinafter, my invention consists of certain novel features of construction, combination and arrangement of parts and portions as will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawing and to the characters of reference thereon which form a part of this application, in which:

Figure l is a plan view of my sprinkler with the jet member removed and the valve member in its normal position; Fig. 2 is a sectional view thereof through 22 of Fig. 1; Fig. 3 is a bottom view thereof from the line 33 of Fig. 2; Fig. 4 is a plan view of my sprinkler with one form of jet member in position and the valve member reversed; Fig. 5 is a sectional view thereof through 5-5 of Fig. 4 with parts and portions shown in elevation to facilitate the illustration; Fig. 6 is a sectional view of the jet mem ber taken through 66 of Fig. 5; Fig. '7 is a sectional view through another jet member having a different shaped orifice; Fig. 8 is a sectional view thereof through 8-8 of Fig. '7; Fig. 9 is a sectional View through 99 of Fig. 10 showing a third jet member; Fig. 10 is a sectional View thereof at right angles to Fig. 9 taken through 10-10 thereof; Fig. 11 is a sectional view through l'111 of Fig. 12, showing a fourth jet member, and Fig. 12 is a sectional view thereof through 1212 of Fig. 11.

Similar characters of reference refer to similar parts and portions throughout the several views of the drawing.

Base member 1, clamp member 2, valve member 3, jet members 4, 5, 6 and '7, constitute the principal parts and portions of my sprinkler.

The base member 1 is provided with an internally threaded lower portion 1a which is adapted to be secured to a suitable outlet of a sprinkling system, not shown. The lower, outer portion of the base member 1 is provided with a polygonal shaped flange 1b which is adapted to receive a suitable tool for securing said base member to the outlet of a sprinkling system. The upper end of the base member 1 is reduced in size and forms a substantially semi-spherical support portion 1 A tapered depression id is provided in the upper side of said semi-spherical portion 10. The depression 1d communicates with the internally threaded portion 1a and with the sprinkling system by means of a passage 1e which is internally threaded to receive a valve member 3.

The outer periphery of the base member 1 above the polygonal flange 1b is threaded to receive a clamp member 2. The clamp member 2 has a passage therethrough, the upper portion of which is constricted. The under side of said constricted portion forms a shoulder 2a which may conform to the shape of the semi-spherical portion 10 of the'base member 1 or may conform to the outer peripheries of the jet members, to

be described later, but said shoulder is preferably made frusto-conical so as to engage the jet member used at the extended edge of said shoulder, as shown in Fig. 5. The constricted portion above the shoulder 2a tapers outwardly forming a frusto-conical aperture 212. The upper portion of the clamp member 2 is provided v may, if desired, be used without the jet member.

The valve member 3 is threaded at its one end portion 3a. The threaded portion terminates in an inwardly tapering central or neck portion 3b. The neck portion 3b in turn merges into a head portion 30 having a slit 311 in its top side for receiving a screw driver. A passage 3c is provided in the valve member which extends from the threaded end thereof into the neck portion 3b thereof, where said passage 3c is intersected by two downwardly and inwardly extending passages 3 which also intersect the walls of the neck portion 3b.

The neck portion 3b together with the walls of the passage 1c in the base portion 1 regulate the amount of water which can pass through the passages 3 The head 30 together with the tapered recess 101 form an orifice the size of which is regulated by turning the valve member one direction or the other.

With the structure shown in Figs. 1, 2 and 3, the sprinkler is especially adapted for the central portions of lawn or other places where it is desired to sprinkle an equal distance in every direction. In this structure, the tapered or conical aperture 212 serves to deflect the misdirected water.

While the valve member 3 normally remains in the position shown in Figs. 1 and 2 when used in conjunction with the jet member, it may be reversed in the manner illustrated in Figs. 4 and 5, in which case it may, if required, be adjusted by means of the oppositely positioned lengthwise extending grooves 3g into which a screwdriver may be inserted after removal of the clamp memher 2 and the jet. The inverted position, is, however, used preferably only when full strength of spray is required, the valve 3 occupying the lowered position shown in Fig. 5 in order to provide 7 the maximum opening.

In the complete structure shown in Figs. 4 and 5-, a jet member 4 which is a semi-spherical shell, is clamped between the semi-spherical portion 10 of the base member and the shoulder 2a of the clamp member 2. The jet member forms with the spherical portion of the base member a ball and socket joint which permits the orifice 4a of the jet member to be shifted from one side to the other relative to the tapered aperture 21), thereby changing the direction and distance covered by the spray.

The orifice 4a is preferably formed by extruding the central portion of jet member with a punch having a sharpened edge causing it to make a slit. Other shaped orifices may be provided as indicated in Figs. 7 to 12 inclusive.

The spray member 5 shown in Figs. '7 and 8, directs the water in two opposite directions so as to sprinkle a relatively narrow, long area. The jet 6, shown in Figs. 9 and 10, is provided with three orifices, while the jet 7, shown in Figs. 11 and 12, is provided with four. Thus it can be seen that the jet members may be provided with orifices most suitable for the position of the sprinkler.

By slightly loosening the clamp member 2 and shifting the jet members, it is possible to accurately direct the water. It will be noted that the sprinkler need be only slightly larger than the outlet pipe of the sprinkling system. Thus the sprinkler is practically unnoticeable and unobstructive.

Though I have shown a particular construction, combination and arrangement of parts and portions, and certain modifications thereof, I do not wish to be limited to this particular construction, combination and arrangement, nor to the modifications, but desire to include in the scope of my invention the construction, combination and arrangement substantially as set forth in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a sprinkler, a base member seourable to an outlet of a sprinkling system, a shiftable jet member forming a ball and socket joint with said base member, and a clamp member for securing said jet member in position, said clamp member including an inner peripheral portion diverging from said jet member, said inner peripheral portion forming a deflecting surface for assisting in the directing of fiuid issuing from said jet member.

2. In a sprinkler, a jet member in the form of a semi-spherical shell provided with an outlet orifice in the crown of said shell, and clamp members for said jet member, the one clamp member constituting atubular base connectible with an outlet of a sprinkling system and including a rounded end fitting into the concave or inner side of said jet member, the other clamp member screwable upon said one clamp member and including a constriction having converging side walls, the smaller diametered portion of said constriction arranged to bear against the outer or convex portion of said jet member, the walls of said constriction outwardly of said jet member forming diverting and distributing surfaces for water issuing from said jet member.

3. In a sprinkler, the association with a base connected with a terminal outlet of a sprinkling system, of a jet member comprising a semi-spherical body portion, a cup shaped extrusion formed in the crown of said body portion disposed with its convex side facing the concave side of said body portion, and jet orifices provided between the periphery of said extrusion and the adjacent margin of said body portion.

4. Ina sprinkler, a jet member comprising a semi-spherical body portion, an extrusion formed in the crown of said body portion, webs connecting said extrusion by its periphery with said body portion, and jet orifices formed between said webs, the under or inner surface of said extrusion being convex for deflecting water into and through said jet orifices, and clamping means for universally mounting said jet member, said clamping means arranged to be connected to a terminal of a sprinkling system.
